FFmpeg总结（十一）用ffmpeg进行转格式，Android下播放网络音频流

思路：
1、mp3转成pcm(音频数据)，ffmpeg做的事
2、OpenSL ES引擎创建AudioPlayer，实际调用了AudioTrack

遇到的错误：
Error #include nested too deeply
原因：c文件互相引用
解决方案：

• 1、将两个头文件共用的那一部分抽出来单独建一个头文件。
• 2、加预处理#ifndef.. #define…#endif

x86平台没有编译出来so，怀疑存在版本不兼容，编译别的相关so，x86下没有异常。有空这里再更新下原因

studio写ndk相当方便：

工程结构：

Java代码：

package com.hejunlin.ffmpegaudio;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.EditText;import android.widget.TextView;public class MainActivity extends AppCompatActivity {    private EditText mInput;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mInput = (EditText) findViewById(R.id.et_input);     mInput.setText("http://qzone.60dj.com/huiyuan/201704/19/201704190533197825_35285.mp3");        findViewById(R.id.bt_play).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                NativePlayer.play(mInput.getText().toString().trim());            }        });        findViewById(R.id.bt_pause).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                NativePlayer.stop();            }        });    }}

NativePlayer:

package com.hejunlin.ffmpegaudio;/** * Created by hejunlin on 17/5/6. */public class NativePlayer {    static {        System.loadLibrary("NativePlayer");    }    public static native void play(String url);    public static native void stop();}

通过cmake，或ndk-build都可以编译，会生成一个NativePlayer.so
